This paper introduces the application about anchor cable jetting combined supporting in broken soft rockdrift.
重点介绍了锚索喷注联合支护在碎胀软岩巷道掘进中的应用。

The system model based on computer aided design and expert system techniques is established through analytical studying on the engineering data of rockdrift tunneling.
通过对岩巷掘进工程资料的分析研究，建立了基于辅助设计和专家系统技术的系统模型。
